3 Claims. (01 101220) This invention relates to the drive of a printmg press. I

The principal object of the invention is to provide a drive in which the driving motor is located 5 where it will take up no space beneath the pressfloor and no head room above the press unit and no floor space elsewhere. The invention has for its secondary object the driving of the press from a motor in as close proximity as possible I to the cylinder of the press which it drives, thus I avoidinga comparatively long transmission of power.

Other objects and advantages of the invene tion will appear hereinafter. 7

Reference is to be had to the accompanying drawing, in which Fig. 1 is a side view, partly in section, of the printing couples of a printing press, showing the drive arranged in accordance with this invention, and

Fig. 2 is a similar view showing a modification of the means for transmitting power from the motor to the cylinder.

The saving of space in a press room is becoming more and more important as printing presses are enlarged and attempts are made to put the enlarged presses in the same spaces occupied by the old ones. It is necessary therefore to avoid the taking up of additional floor space by the motor and also these presses are being made so tall that it is'important to save the 'head room occupied by a motor located at the top of a press. Even the room required beneath the press floor for a motor when placed below the press is disment of room in the places indicated is avoided. In the iorm shown in Fig. l, the press unit is arranged in such a way that the driving motor 10 is attached to a brace ll of the press frame inder shaft. The rest of the unit is driven in any desired way by gear or chain connections from the first impression cylinder.

As stated, the motor is located close to the first impression cylinder 12 and between the two inking mechanisms 14 in a space not heretofore occupied. This arrangement provides for the utilization of this previously wasted space and avoids the necessity of mounting the motor pressed in the claims.

, respect,'but what I do claim is:

driving one of the. cylinders of .theprinting advantageous. By this invention, the employ-" the form shown in this figure, is by a chain 13 and sprockets on the motor shaft and the cyloverhead or underneath or on the floor which supports" the press. The drive is direct and avoids the employment of shaftsbetween the motor and the impression cylinder as well as excess transmission means, thereby simplifying 0- themechanism. This permits of the construc tion of a very compact press unit which may be placed in a relatively small space.

Each unit is driven with a separate motor. All of the motors of the combination are held 5 in synchronism to keep thepapers properly registered. r

In the form shown in Fig. 2, everything said above applies. The drive from the motor 10 to r the cylinder 12 is by means of gearing 1 whichf makes the construction equally compact and gives the same advantages.

Although I have illustrated and describedonly jtWO forms of the invention, I am aware of the fact that other modifications can be made there- '75 in by any person skilledin the art without departing from the scope of the invention as ex- Therefore I do notfwish to be limited this 1.

ZLYIn a printing press unit, the combination of the printing couplesand inking mechanism located below the printing cylinders; of a motor located inside the press in the space between the inking mechanisms and connected directly with one of the cylindersfor driving the entire unit. 3.
